/* ** ** Swift/XRT hardness ratio for BL Lacertae. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 56435.727696 0.000761 0.48429 0.13345 0.94677 0 0.46188 0.07349 0.32922 0.05237 0.22368 0.05033 0.15998 0.03599 56435.729131 0.000674 0.49097 0.13572 0.97425 0 0.49692 0.07982 0.35734 0.05740 0.24397 0.05489 0.17549 0.03948 56435.730537 0.000732 0.58824 0.16792 0.98024 0 0.38158 0.06771 0.27415 0.04865 0.22446 0.05019 0.16156 0.03613 56435.731874 0.000605 0.97050 0.30690 0.97129 0 0.28174 0.06300 0.20338 0.04548 0.27343 0.06114 0.19737 0.04413 56435.733075 0.000596 0.59994 0.17457 0.96117 0 0.45407 0.08058 0.32757 0.05813 0.27242 0.06282 0.19653 0.04532 56435.734287 0.000616 0.55606 0.15667 0.96244 0 0.48427 0.08214 0.34943 0.05927 0.26928 0.06058 0.19432 0.04372 56435.736183 0.001279 0.51890 0.11362 0.96380 0 0.40400 0.05182 0.29022 0.03722 0.20963 0.03720 0.14994 0.02661
